Engine And Engine Cooling Problems of Lexus LX

I am filing this complaint regarding the handling of safety recall 25la07 (NHTSA recall id 25v767) affecting my 2023 Lexus Lx600. On January 2, 2026, I delivered the vehicle to the authorized Lexus dealer in ponce, puerto rico, in response to the recall, which identifies potential engine knocking, rough running, engine no-start, and/or loss of motive power. These conditions represent serious safety risks. Since that date, the vehicle has remained at the dealership. More than five weeks have passed, and neither the dealer nor Lexus has provided a definitive remedy, technical instructions, or a timeframe for repair. We have been told they “do not yet know” whether the solution will involve reprogramming or full engine replacement. In short, there is no clear plan or expected completion date. Because the manufacturer has acknowledged a potential engine malfunction and the increased risk of crash, my wife does not feel safe operating the vehicle. The general manager told us to keep driving the vehicle until there is any signs of malfunction of the engine, however after consulting legal counsel, we were advised not to retrieve the vehicle until the defect is fully corrected and certified as safe. Although Lexus provided a Mitsubishi rental vehicle, it is materially inferior to the Lx600. Meanwhile, I continue making substantial monthly payments to Toyota financial services for a vehicle that has been unusable since January 2, 2026. The manufacturer is covering the rental cost (approximately half of my monthly payment), but I remain financially responsible for a luxury vehicle that cannot be used and for which no repair timeline exists. I respectfully request that NHTSA review whether the manufacturer is meeting its obligation to provide a timely and effective remedy for this safety recall. I am prepared to provide supporting documentation upon request.

Description of incident: this is a recurring safety defect that has occurred multiple times from August 2023 to February 2026. The following description refers to the most severe incidents: 1. Nature of defect: the vehicle experienced a sudden "limp mode" event where all dashboard warning lights illuminated simultaneously, followed by an immediate loss of propulsion while in motion. Subsequently, the vehicle suffered from a dangerous 3-second acceleration lag/delay. This 2023 Lexus Lx 600 creates a life-threatening risk on public highways, as the driver cannot reliably control the vehicle's speed or power to avoid collisions. 2. Manufacturer’s admission: the vehicle has been presented to authorized Lexus dealerships. While the dealership could not provide a permanent fix, the manufacturer’s own internal tracking system now explicitly confirms: "remedy: not available. " this is a formal admission by Lexus/Toyota that the vehicle has a catastrophic system failure with no known fix. 3. Requested action: Lexus/Toyota has refused to repurchase the vehicle, forcing me to drive a dangerous asset they admit they cannot repair. I request that NHTSA immediately initiate a safety investigation into this loss of propulsion and acceleration lag issue for the 2023 Lexus Lx 600, especially given the "no remedy" status. A mandatory recall is warranted.

The contact owns a 2023 Lexus Lx 600. The contact received notification of NHTSA campaign number: 25v767000 (engine and engine cooling). The contact called the dealer and the manufacturer and was informed that the remedy was not yet available. The contact stated that the dealer and the manufacturer offered a stipend for a rental. The contact deferred on renting a vehicle. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The contact had not experienced a failure.

I am writing to report a concern regarding an unresolved safety recall for my 2023 Lexus Lx 600. Lexus notified us of this recall on November 6, 2025. However, nearly four months later, the company continues to state on its website that no remedy is currently available. Given the significant purchase price of this vehicle—exceeding $100,000—I find it unacceptable that a resolution has not yet been provided. I respectfully request that this matter be reviewed and that appropriate action be taken to ensure a timely and effective remedy for affected customers.

My car suffered complete engine failure at 25,522 miles. Lexus claims that it is not in the VIN range of the recall. However, it is the exact same problem all other 2022-2023 Lx600 are experiencing and being recalled for. Lexus is clearly minimizing the extent of the engine failure issue and my VIN is also part of the problem.

My problem occurs intermittenly, it occurs when I am idling at a stop. When I have to accelerate from the stop the car will lurch forward and die for approximately 3 seconds. It will then restart and drive normally, however the stopping in the middle of oncoming traffic is potentially life threatening. It has occurred approx 8 times since I bought the car in June 2023. I had the eco recall done and it also occurred shortly after that. I have taken it back to the dealer and they could not recreate the problem. It occurs after idling and waiting and then accelerating quickly to merge.

My car has had a rough idle off and on for 1 year. What is really scary is that 2 times in the last two weeks I have lost engine acceleration when pulling into traffic.

I have had several incidents of having to accelerate quickly and the engine stalled out. I reported it to the dealership and they claimed they could not recreate it and sent me on my way. Now that there is a supposed recall I would like to get my motor replaced or at least scheduled ASAP.

2008 Lx570: this is my second time owning a Toyota/Lexus vehicle with the 3ur-fe/5. 7l v8 and each has had the same issue. At 156,000 miles, noticed a nauseating smell of oil and coolant enter the cabin via the air vents. Noticed oily residue around front and sides of engine, no check engine lights. Took vehicle to Lexus dealer who reported that timing and valve covers were leaking oil and that the valley plate/heat exchanger was leaking coolant. The smell of oil and coolant entering the cabin caused me and my occupants to become nauseated and dizzy while traveling with the air on. Total estimated amount of repairs, $5,400. Was informed by Lexus service tech that the Toyota/Lexus sealant around timing cover and heat exchanger/valley plate were defective and that this would happen to all engines of this class (3ur-fe/5. 7). Contacted Lexus customer care and was advised that due to vehicle being out of warranty, there was no concern to offer any incentive toward repair, regardless of the intoxication/inebriation that passed from the engine bay into the cabin. Toyota/Lexus refuses to issue a campaign or customer incentive program to resolve this issue. This is a very costly repair that can harm the lives of others via poisonous run-off that occurs when oil and antifreeze leak onto the engine while at time, causing fumes to pass from the engine bay to the cabin via the air vents. Another safety issue if this is left untreated would be the engine running completely out of oil and antifreeze, causing vehicle and occupants to become stranded. This is also a fire hazard with oil leaking onto a hot engine while at temp.
